.net XmlSerializer 上覆盖的属性 [英] .net XmlSerializer on overridden properties

问题描述

我有一个带有抽象属性的基类:

I have a base class with an abstract property:

public abstract int ID {get;set;}

现在，我有一个子类，它是 XmlSerialized.所以，它有:

now, I have a subclass, which is XmlSerialized. So, it has:

[XmlElement("something")]
public override int ID {
get { //... }
set { //... }
}

我无法将 XmlElement 属性移动到基类，因为每个子类都有不同的 xml 元素名.

I cannot move the XmlElement attribute to baseclass, since every subclass will have a different xml elementname.

现在，当我反序列化此类时，出现以下错误:

Now, when I deserialize this class I get the following error:

成员 'Subclass.ID' 隐藏继承成员BaseClass.ID"，但有不同的自定义属性.

Member 'Subclass.ID' hides inherited member 'BaseClass.ID', but has different custom attributes.

我能做什么?

推荐答案

当被覆盖的属性有 [XmlElement] 和 [XmlAttribute] 时，派生类型的序列化和反序列化工作属性，通过添加 [XmlIgnore] 属性.

Serialization and deserialization of derived types works when the overridden properties have [XmlElement] and [XmlAttribute] attributes, by adding an [XmlIgnore] attribute.

基类可以被抽象化，这样它就不能被实例化，因此不能被序列化或反序列化.

The base class can be made abstract so that it can never be instantiated and therefore serialized or deserialized.

[Serializable]
public abstract class Base
{
    [XmlIgnore]
    public abstract Int32 ID { get; set; }
}
